Asynchronous Message The Linda Experience Interrupt and Lost Message Bibliography

CONTENTS

1. Not existing or occurring at the same time.

2. Pertaining to a transmission technique that does not require a common clock between the communicating devices;

3. Without the use of fixed time intervals

1. Asynchronous

A message is information which is sent from a sender to a receiver.

Message

Passing

Passing is a way which going through one step to

another.

How it work…

Asynchronous…

Example of Asynchronous Message

Linda Experience

Linda is based on a global mailbox or a bulletin board.

This is done through the use of tuple space which is logically shared by all concurrent processes.

Tuple space behaves like a bulletin board and global mailbox.

Concurrent programming works in Linda and tuple space is implemented on either shared-memory multiprocessors or distributed-memory multicomputer.

Message passing….

Interrupt and Lost Messages

Interrupt message are a special form of asynchronous message handling.

Message are often lost in a message passing system.

Special detection algorithm or debugging tools are needed to inspect message buffers and to correct possible system configuration or programming errors.
